Compact floribunda rose plant named ‘Poulac014’

ABSTRACT

A new garden rose plant of the compact floribunda class which has abundant, apricot flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrida.

Variety denomination: ‘Poulac014’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant which originated from a controlled crossing between thefemale seed parent plant, an un-named seedling, and the male pollenparent plant, an un-named seedling. The two parents were crossed duringthe summer of 1995 and the resulting seeds were planted in a controlledenvironment in Fredensborg, Denmark. The new variety is named‘Poulac014’.

The new variety may be distinguished from its unnamed female seedparent, by the following combination of characteristics:

-   -   1. While the seed parent has yellow flowers, ‘Poulac04’ has        apricot flowers.    -   2. While the seed parent has acute flower petal bases,        ‘Poulac014’ has rounded to acute flower petal base shapes.

The new variety may be distinguished from its male pollen parent by thefollowing combination of characteristics:

-   -   1. ‘Poulac014’ has larger leaves than those of the pollen        parent.    -   2. ‘Poulac014’ has larger flowers than the pollen parent.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant apricot flowers;    -   2. Vigorous, but compact growth when propagated both as a budded        rose and on its own roots;    -   3. Disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘Poulac014’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and MogensN. Olesen germinated the seeds from the aforementioned hybridizationduring winter of 1995 and conducted evaluations on the resultingseedlings in a controlled environment in Fredensborg, Denmark.

‘Poulac014’ was selected in the spring 1996 by the inventors as a singleplant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulac014’ by traditional budding and rootedcuttings was first done by L. Pernille and Mogens N. Olesen in theirnursery in Fredensborg, Denmark in July, 1996. This initial and othersubsequent asexual propagations conducted in controlled environmentshave demonstrated that the characteristics of ‘Poulac014’ are true totype and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulac014’, as observed in its growthin a field nursery in Jackson County, Oreg. Observed plants are 3 yearsof age. Plants were grown on Rosa multiflora understock. Colorreferences are made using The Royal Horticultural Society (London,England) Colour Chart, 1995, except where common terms of color areused.

For a comparison, several physical characteristics of the rose variety‘Poulymp’, a rose variety from the same inventors described andillustrated in U.S. Plant patent application Ser. No. 09/607,327 datedJun. 30, 2000, are compared to ‘Poulac014’ in Chart 1.
